THUNDERHEAD RANKED IN THE 2021 DELOITTE TECHNOLOGY FAST 50

Leader in technology for Customer Engagement and Journey Orchestration named one of the fastest-growing technology companies in the UK for the second consecutive year.

Thunderhead today announced its inclusion in the 2021 Deloitte UK Technology Fast 50, a ranking of the 50 fastest-growing technology companies in the UK. Rankings are based on percentage revenue growth over the preceding four years. Thunderhead grew 882 percent during this period, and attributes its growth to the rapid adoption of its customer journey analytics and journey orchestration platform that drives customer engagement for global enterprise brands. Thunderhead CEO Glen Manchester credits their impressive customer success globally across multiple industry sectors to the company’s unique fusion of AI-driven journey orchestration and real-time interaction management. He commented, “As a pioneer and leader in journey-based customer engagement, our growth reflects the massive market demand for our new generation of technology, which unites and orchestrates all conversations and journeys between a brand and its customers. This concept lies at the heart of our Customer Operating System™ (CoS), replacing outdated legacy and siloed technologies with a new era of autonomous orchestration.”

Duncan Down, lead partner for the Deloitte UK Technology Fast 50 programme, said: “The extraordinary growth of this year’s Fast 50 represents the remarkable tenacity of the UK’s technology industry. Deloitte’s 2021 Fast 50 awards are a clear demonstration of the wealth of talent, creativity, and entrepreneurship in the UK’s technology industry today.”
